Description
Technical Field
The utility model belongs to the technical field of new forms of energy electric automobile, concretely relates to high voltage distribution box body.
Background
New energy electric vehicles are rapidly developed under the strong support of national policies. Generally, running under high-power vehicle power has great challenges to the design of high-voltage distribution systems and the selection of high-voltage components. In view of the space of the whole vehicle and the complexity and cost of the whole vehicle structure, the industry widely adopts the centralized high-voltage electrical system structure for power distribution. The high-voltage power supply of the power battery of the new energy electric automobile directly enters the high-voltage distribution box and then is distributed to system high-voltage electric products according to system requirements, the high-voltage distribution box on the market at present mostly adopts the design concept of an industrial high-voltage distribution box, the industrial high-voltage distribution box is used for installing components in a mode of combining a guide rail with a wire groove, and the flatness of power supply contact points among the components is not required to be controlled. However, each component of the high-voltage box of the new energy electric vehicle is connected through the hard copper bar, so that the flatness of the power supply contact point is necessarily considered, and the hard copper bar is used for connection due to the cost, so that the cost of the soft copper bar is high.
The integrally formed high-voltage distribution box needs die sinking production, and is huge in early investment and incapable of guaranteeing benefits, so that the high-voltage distribution box needs to be processed in a large quantity of full-welding splicing modes in the production process, is very easy to be heated and deformed, and cannot guarantee the flatness of power supply contact points among all components on the same horizontal plane; the stress of the power supply contact points of the components is uneven, the service life of the components is shortened due to heating, the contact internal resistance is increased due to uneven contact surfaces, and burning accidents are caused in severe cases. Therefore, it is difficult to satisfy the requirements of the automobile in terms of safety, reliability and durability by fully welding a large number of high-voltage electric boxes which are easy to deform.
Disclosure of Invention
The utility model aims at providing a high voltage distribution box body to the problem of the power contact point roughness on same horizontal plane between each components and parts can't be guaranteed to new forms of energy electric automobile's current high-voltage box.
In order to achieve the above object, the present invention provides the following technical solutions:
the utility model discloses a box body and components and parts mounting panel, the bottom surface of components and parts mounting panel is fixed at four fixed points that distribute along circumference with the bottom plate medial surface of box body, the fixed knot that four fixed points punishment were all the same, and adopt one of following fixed knot to construct in ① components and parts mounting panel sets up four step holes that distribute along circumference, sets up four screw holes on the bottom plate of box body, and the central axis one-to-one of screw hole and step hole aligns, the top hole section aperture in step hole is greater than bottom hole section aperture, and the screw hole that every step hole aligns with the position is through a screw connection, and the head of screw is placed in the top hole section in step hole, ② every fixed point department is equipped with a solder joint.
The utility model discloses beneficial effect who has:
with components and parts assembly the utility model discloses an on the components and parts mounting panel, because the utility model discloses only it is fixed to adopt screw or solder joint form in four fixed points department, and the roughness is guaranteed easily, can effectively avoid protruding or sunken in the middle of the box body to effectively avoid current high voltage distribution box to cause the problem of components and parts mounted position department deformation because of the mode processing of a large amount of full weld splices, fall deformation volume to minimum, and play the effect of certain whole high voltage distribution box of strengthening.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 1, the high-voltage distribution box comprises a box body 1 and a component mounting plate 2, wherein the bottom surface of the component mounting plate 2 is fixed to the inner side surface of the bottom plate of the box body 1 at four fixing points which are uniformly distributed along the circumferential direction, the fixing structures at the four fixing points are the same, one of the fixing structures is adopted, ① component mounting plates 2 are provided with four step holes which are uniformly distributed along the circumferential direction, the bottom plate of the box body 1 is provided with four threaded holes which are aligned with the central axes of the step holes one by one, the pore diameter of the top hole section of each step hole is larger than that of the bottom hole section, each step hole is connected with the threaded hole which is aligned with the position through a screw, the head of the screw is placed in the top hole section of each step hole, and ② is provided with a welding point at each fixing point, namely the box body 1.
And assembling the component 3 on the component mounting plate 2 of the high-voltage distribution box body. Because this high voltage distribution box body only adopts screw or solder joint form fixed at four fixed points department, the roughness is guaranteed easily, can effectively avoid protruding or sunken in the middle of the box body to effectively avoid current high voltage distribution box to cause the problem of 3 mounted position departments of components and parts deformation because of the mode processing of a large amount of full weld splices, reduce the deformation to minimum, and play certain effect of strengthening whole high voltage distribution box.
